a friend of mine suggested i do a reamer job on my 260 remington and turn it into a 260 ackley improved. sounds like a good idea to me. they do a reamer job on the chamber and refit the barrel. i would have to fireform the new cases from normal 260 cases and reload for the 260 AI. they have a 40 degree shoulder then and are basicaly straight cases. the 260 AI should get me about 100-150 fps more. anyone have reloading date for a 260 ackley improved? what are your thoughts on this?
